Sioux Falls to Springfield Road Trip: Complete Guide

The route from Sioux Falls, South Dakota to Springfield, Illinois spans approximately 580 miles of America's heartland, following I-29 south to I-80 east, then I-155 and I-72 into Springfield. A lesser-known fact: the route crosses the ancient shoreline of Glacial Lake Agassiz, whose flat lakebed makes eastern South Dakota and northwestern Iowa some of the flattest farmland on Earth. This drive typically takes 9-10 hours without stops, but the real value lies in the detours and discoveries along the way.

Fuel and Route Economics

Gas prices along the I-29/I-80 corridor tend to be lower in Iowa and Illinois than in South Dakota. Fill up in Sioux Falls (approx. $3.20/gal) and again near Des Moines or the Quad Cities. Avoid truck stops on the outskirts of big cities; prices often spike. A mid-size sedan will need three fill-ups for the one-way trip.
